How to use WS2812 for at32 mcu's.

[smollion1]

I tried adding ws2812 to the tekko32 target circuit, using version 1.99 firmware, but it didn't work

Did you try below macro for definition?

#define USE_LED_STRIP
#define WS2812_PIN GPIO_PINS_7

Be aware of change the pin number according to your sch.

ok
In the target of F051, USE_RGB_LED is defined. Which pin is used?

[lida2003]

It needs to be checked with tekko32, so you have to contact manufacture for more sch info I think.

Currently, I just saw two targets have this feature:

• FLYROTOR_F421
• HAKRC_G23_F421

[smollion1]

The LED of F421 is already on, but the LED of F051 seems different. USE_RGB_LED，but not define pin.

• #ifdef NEUTRONRC_F051
• #define USE_RGB_LED

Check schmatic and make sure the pin is on the board
